changes
* **v1.1.1**: Added new documentation, including annotation properties (e.g., `bibo:doi`, `schema:codeRepository`, etc.), term properties (e.g., `vann:example`, `vs:term_status`, etc.), exemplary competency questions with their respective SPARQL queries, and a Grafoo diagram.

description
This is an additional module of BiDO that extends the class `bido:CategorialBibliometricData` of the core module with specific categories describing the research career of people. ![The architecture of BiDO-Research-Career-Category module.](bido-research-career-category.png) These categories are described by the class `bido:ResearchCareerCategory`, which is characterised by four specific dimensions that have been used by our algorithm to cluster citation data: * the _research period considered_, i.e., the interval of research years that the algorithm is taking into consideration (e.g., the first 5/10 years); * the _curve_, i.e., the specific shape proper to the clusters identified by the algorithm, which is characterised by a trend (flat/increasing/decreasing) and, in the latter two cases, by an acceleration or deceleration point (none or premature, median, overdue acceleration/deceleration); * the _slope_ of such curve, in terms of strength (low/moderate/high) and kind of growth (linear/polynomial/exponential/logarithmic); * the _order of magnitude_, which categorises the number of citations received in the considered period according to a uniform model of common-sense estimation [1], which describes intervals of half-order of magnitude – i.e., “[0,1)”, “[1,3)”, “[3,9)”, “[9,27)”, “[27,81)”, “[81,243)”, “[243,729)”, etc.
